Switching between multiple SDI, HDMI and DVI sources in real time calls for a dedicated video mixer, and this range covers compact multi-channel units such as the AvMatrix PVS0615 and HVS0402U alongside broadcast-grade switchers from Roland, Kramer and Barco. These devices allow operators to cut, mix or fade between cameras, playback devices and graphics feeds, routing a chosen signal to a single programme output for recording or live display.
Such equipment is typically deployed in live events, broadcast trucks, studio productions and conference or presentation setups where several video sources need to be combined or switched seamlessly. Flight cases are included for transport and protection on the road. Formats and channel counts vary across the models listed, allowing selection according to the number of inputs and signal types a production requires.
